ENZYMEEnzyme nomenclature database

ENZYME is a repository of information relative to the nomenclature of
enzymes. It is primarily based on the recommendations of the Nomenclature
Committee of the International Union of Biochemistry and Molecular Biology
(IUBMB) and it describes each type of characterized enzyme for which an EC
(Enzyme Commission) number has been provided [More details / References
].

ENZYME now includes entries with preliminary EC numbers. Preliminary EC
numbers include an 'n' as part of the fourth (serial) digit (e.g. EC 3.5.1.n3).
